Pilot Study of Reparixin for Early Allograft Dysfunction Prevention in Liver Transplantation
A Multicenter, Open-label, Randomized Pilot Clinical Study of Efficacy and Safety of Reparixin for Prevention of Early Allograft Dysfunction in Patients Undergoing Orthotopic Liver Transplantation
Liver transplantation is currently the treatment of choice for end-stage liver cirrhosis of different origin, as well as for a number of inborn metabolism disorders and liver tumors. The need to perform a liver transplantation is high and amounts to 10 - 20 patients per 1 million population per year.
Experimental and clinical evidence demonstrate the harmful short and long-term effects of ischemia-reperfusion injury (IRI) of the donor organ on the outcome of the intervention performed. Severe manifestations of IRI of the liver transplant (LT) is one of the main reasons for the increased length of hospitalization, the high cost of treating patients during the post- surgery period, the development of persistent early allograft dysfunction or loss, frequent crises of acute rejection, acute renal and multiple organ failure, and mortality of the operated patients.
This pilot clinical study is designed to evaluate the efficacy and safety of Reparixin, which is a new, potent and specific inhibitor of chemokine CXCL8 (Interleukin-8), as an agent to prevent early allograft dysfunction caused by ischemia-reperfusion injury in patients undergoing orthotopic liver transplantation.

Detailed Description
Liver transplantation is currently the treatment of choice for end-stage liver cirrhosis of different origin, as well as for a number of inborn metabolism disorders and liver tumors. The need to perform a liver transplantation is high and amounts to 10 - 20 patients per 1 million population per year. The indication for liver transplantation is the presence of irreversible liver disease with estimated life expectancy of less than 12 months, absence of another treatment, presence of chronic liver disease, significantly reducing the patient's quality of life and ability to work, as well as progressive liver disease with a life expectancy less than in the case of liver transplantation (after liver transplantation 85% of patients survive for 1 year and 70% - for 5 years).
Currently, about 200 liver transplantations are performed annually in Russia, which is more than 10 times lower than the existing need and is far below the number of similar operations performed abroad.
The vast majority of liver transplants for adult recipients are performed using liver allografts from cadaveric donors. The rigorous list of requirements for a transplant restricts significantly the use of cadaveric liver. Thus, the need to expand the pool of donor organs suitable for transplantation is a pressing issue.
Experimental and clinical evidence demonstrate the harmful short and long-term effects of ischemia-reperfusion injury (IRI) of the donor organ on the outcome of the intervention performed. Severe manifestations of IRI of the liver transplant (LT) is one of the main reasons for the increased length of hospitalization, the high cost of treating patients during the post- surgery period, the development of persistent early allograft dysfunction or loss, frequent crises of acute rejection, acute renal and multiple organ failure, and mortality of the operated patients. IRI caused by the termination and subsequent restoration of blood flow is more or less inevitable for all donor organs. The mechanism of ischemia-reperfusion syndrome involves interaction between vascular endothelium, interstitial space, circulating cells and a variety of biochemical reactions, with the primary link in the chain of pathological processes of local and generalized nature being microcirculatory disorders. Early allograft dysfunction is an important predictor of severe complications and mortality after OLT.
The incidence of early allograft dysfunction is approximately 25% (ranging from 9.3 to 43.7% subject to different definitions and classifications of the condition). Retrospective evaluation of the incidence of early allograft dysfunction performed in the Russian leading transplantation institution - N.V. Sklifosovsky Research Institute of Emergency Care, confirmed the development of this type of complication in 25% of cases (N = 202). Death has occurred in the population of patients with early allograft dysfunction at almost twice the rate of patients with normal functioning of the transplant during the first 7 days after OLT (p < 0.005).
Therefore, as yet, the search of the drugs that may be effective in the prevention of early allograft dysfunction is still a relevant issue.
Reparixin is a new, potent and specific inhibitor of chemokine CXCL8 (Interleukin-8). With regard to the mechanism of action of Reparixin, its early preclinical development was aimed at specific inhibition of migration of polymorphonuclear neutrophils and prevention of ischemia- reperfusion injury.
Reparixin has received the orphan drug designation in EU in September 2001 and in USA in January 2003 for prevention of delayed graft function after solid organ transplantation. More recently orphan drug designation has been granted in EU (September 2011) for the "prevention of graft loss in pancreatic islet transplantation" and in the US (September 2012) for the "prevention of graft loss in islet cell transplantation".
This pilot clinical study is designed to evaluate the efficacy and safety of Reparixin as an agent to prevent early allograft dysfunction caused by ischemia-reperfusion injury in patients undergoing orthotopic liver transplantation.

Inclusion Criteria:
- Male and female patients aged 18 years and older needing a whole organ OLT, listed on the waiting list for liver transplantation.
